Deep-sea expedition led researchers to doomed octopus nursery

The ill-fated octopods may be a sign that a healthy population is hiding nearby.

A robotic fish could help mangroves grow

Reforested mangroves don’t always grow well. To figure out why, two teens built a robotic mudskipper to measure the mud.

‘Boot camp’ teaches rare animals how to go wild

Animals raised in captivity cannot safely re-enter the wilds without first understanding how to find food and avoid becoming a predator’s lunch. Scientists are helping some species learn this.

Small swimmers may play huge role in churning the seas

Hoards of migrating shrimp and krill can cause large-scale water movements in the ocean, a new study suggests.

Migrating crabs take their eggs to the sea

Cuba’s colorful land crabs connect swamp and sea with their yearly mass migrations. Protecting their routes can help other animals too.

Genetics

Can DNA editing save endangered species?

Scientists may be able to help endangered species by changing the genes of a whole population of wild animals. But some question whether that is wise.

Blooms on ‘chocolate’ tree are crazy-hard to pollinate

The cacao trees must be pollinated or those seeds that give us chocolate will never form. The rub: The trees’ flowers challenge all but some of the tiniest pollen-moving insects.

Here’s why scientists have been fertilizing the Arctic

For more than 30 years, scientists have been fertilizing small parcels of Arctic tundra. Here’s what happens when you push an ecosystem to the brink.

Ecosystems

Scientists Say: Bog

Bogs are a type of wetland in which partially decayed plants sink down and form peat.
